Methods: The study was conducted over a 1 month period from August 1, 2014, to September 1, 2014. All subjects were asked to complete a self-administered questionnaire. A total of 261 questionnaires were used in the final analysis (incorrectly completed questionnaires were excluded). The data was subsequently analyzed (including t-test, one way ANOVA, and Pearson's correlation coefficient) using SPSS version 20.0. Results: In total, 91.6% of respondents were aware of the national health insurance scaling program. Furthermore, 81.8% said that they were satisfied with national health insurance scaling. The majority of the respondents (69.0%) were also satisfied with the national health insurance scaling fee. Although 71.6% were satisfied with national health insurance scaling age, only 60.5% were satisfied with the frequency of national health insurance scaling. The disparity in the reported awareness on scaling and on national health insurance scaling was showed to be statistically significant (p<0.05). Moreover, the reported difference between satisfaction on national health insurance scaling and satisfaction with the scaling experience was also significant (p<0.05). Finally, there was a significant difference between reported awareness on scaling, awareness on national health insurance scaling, and satisfaction with national health insurance scaling (p<0.01).
Conclusions:The results presented in this study reveal that awareness of scaling, awareness on national health insurance scaling and satisfaction with national health insurance scaling are important influencing factors. These results should be carefully considered in any plans to expand preventive dental healthcare clinics. In conclusion, a more systematic oral-health policy (especially regarding scaling) needs to be established to improve national oral health and quality of life.
